METHOD FOR REDUCING TRIFLURALIN VOLATILITY Russian patent published in 2004 - IPC

FIELD: agriculture, herbicides. SUBSTANCE: method involves application of the suspension preparation comprising 2,6-dinitro-N,N- dipropyl-4-trifluoromethylaniline, oxyethylated alkylphenol or oxyethylated higher saturated alcohol as an emulsifying agent. Trifluralin is adsorbed preliminary on highly dispersed amorphous silica or kaolin, or aerosil and fixed by styromal or polystyrene, or lacris as a film-forming agent in the following ratio of components, %: 2,4-dinitro-N,N-dipropyl-4- trifluoromethylaniline, 10-30; oxyethylated alkylphenol or oxyethylated higher saturated alcohol, 15-20; highly dispersed amorphous silica or kaolin, or aerosil, 8-12; styromal or polystyrene, or lacris, 1-3; water, the balance. Invention provides reducing volatility of trifluralin and to enhance its herbicide activity and ecological safety. EFFECT: improved method. 2 tbl, 10 ex
